ip - How do VPN's forward network traffic? (Layer 3 The packet is then looked up again in the routing table and sent out onto the internet (if the VPN is a "full coverage" one then the VPN software must take care to set up the routing table in a way that VPN traffic goes out the real internet-facing interface rather than back to the VPN software). When the encapsulated packet arrives at the VPN Site to Site VPN tunnel is up but only passing traffic in The expected flow for a packet coming to the SonicWall across the VPN is it being marked as Consumed, the forwarded, then forwarded. First the SonicWall will receive the packet from the VPN, then decrypt it which is denoted with the (hc) tag on the Packet Monitor, and finally sent onto the physical wire.

In computing, Internet Protocol Security (IPsec) is a secure network protocol suite that authenticates and encrypts the packets of data to provide secure encrypted communication between two computers over an Internet Protocol network.

The faulty line will affect both VPN and normal traffic, not only IPSec VPN. Packet loss can be due to ISP link, cable or interface issues. If you issue command 'show interface' pointing to the interface used by VPN to send out traffic to remote peer, what is the statistic looks like - interface reset, collisions, errors?

Manage packet captures - Azure portal - Azure Network Maximum bytes per packet: The number of bytes from each packet that are captured. If left blank, all bytes are captured. Maximum bytes per session: The total number of bytes that are captured. Once the value is reached the packet capture stops. Time limit (seconds): The time limit before the packet capture is stopped. The default is 18,000 seconds. Site-to-site IPSec VPN - Packet Pushers Since the B-End is remote, it would be preferable to log over TCP as it would give more certainty as to the source of the packets. However, this can overload the ASA so we are stuck with UDP. We log more information at the A-End end as the traffic doesn’t get encrypted so is less of a burden. A-END Types of Virtual Private Network (VPN) and its Protocols Types of Virtual Private Network (VPN) Protocols: Internet Protocol Security (IPSec): Internet Protocol Security, known as IPSec, is used to secure Internet communication across an IP network. IPSec secures Internet Protocol communication by verifying the session and encrypts each data packet during the connection. IPSec runs in 2 modes: 8.4.1.2 Packet Tracer - Configure and Verify a Site-to
